low fidelity calcium kit, not that great featured

Comments This kit gives a decent idea of what the calcium levels in your tank are, but it's not a high fidelity result. If you're looking for something more specific, get a titration style kit that has a tight precision (even the red sea pro calcium test would be a better solution). This kit is decent enough if you're keeping a fish only or easy coral tank, but if you have a lot of stony corals I'd lean towards something with more accuracy.


Liked about it The calcium test kit comes with everything required to perform the test. The instructions are clear, and performing the measurement is rather simple.


Didn't like First, and I have this complaint about most of these red sea test kits, the packaging is irritating. To store this test kit, you do have to reassemble the packaging to get everything to fit in there. I prefer other brands that have simple boxes where everything can be dumped unceromoniously back together. Also, reading the final results of this kit is not straightforward. You have to measure the number of drops of both reagents together and the use a multiplier to determine the final calcium value. Even then, your fidelity is only with 50ppm. Better to use a kit that has a fidelity within 10ppm, such as the salifert line.

Accurate measurement of Calcium featured

Comments A reasonable value, Red Sea's Calcium Marine Aquariums Test Lab is especially useful for a checking that the tank's calcium levels are high enough (preferably 450ppm). Although the calcium test is slightly more complicated than some other parameter tests, the directions are clear. Fill the graduated tube to 4ml, add 4 drops of Reagent A, add 5 drops of Reagent B (would have been preferable if concentration allowed 4 drops for ease of use) and add drop by drop more Reagent A until the color change matches the easy to read "end" color. Then you have a brief formula to find concentration: sum of Reagent A drops X 50 = Ca++ ppm). A 0.85 fl oz sample of Reef Success Calcium is included to begin raising the calcium level although 0.56 fl oz is required to raise a10 gallons by 50 ppm. The calcium should be added over four days (so you have time to go out and buy a bigger bottle of Reef Success). Weekly addition of 1 mg per 12 gal is recommended for maintaining calcium. Personally, I wouldn't purchase Reef Success but would use calcium hydroxide (kaltwasser of pickling lime) to increase calcium concentrations.


Liked about it Widely available test that give an accurate measurement of calcium. You can avoid "snow" by adding calcium to desired concentration but not add in excess. Clear (though complex) directions leave you feeling as if you are doing a science project. All the necessary supplies are easy to store in the container. Some people would appreciate the sample of Success Calcium supplement to immediately begin to increase calcium after testing.


Didn't like The test would have been easier if the reagent concentrations allowed the directions to read "Add 4 drops" consistently for Reagent A and B to get the "start" color. Some people want a quick and easy test and don't have any interest in reliving lab experiences; no more Bill Nye (the Science Guy) for them. The test tube must be cleaned immediately to prevent sediment from distorting future tests. If the precipitate sits in the vial, a thorough vinegar cleaning is required.

Color change is minimal

General If you need to do a calcium test and don't have a lot of money, it is not a bad choice.


Liked about it Some assistance for calcium level monitoring. Inexpensive.


Didn't like Hard to determine if a color change has occured. It did not last for 60 tests.

Calcium tester

General I've tried API test kits and I like Red Sea kits much better . The testing is a bit easier. Instruction are more clear and detailed


Liked about it It's a Red Sea Product,nice vials,big test cup,everything you need to test, comes with syringe,


Didn't like Using a syringe to add drops is very difficult. If you push to hard the reagent comes out too fast . It's tough to extract the test solution "C" without getting air in the syringe
